Paying attention to the important consequences of repentance, that are gaining forgiveness, mercy and Divine contentment and to be fit to enter into Paradise, to be safe from the torment of Hell, to be away from deviation and straying, to follow the right path and the way of guidance, to be pure from the darkness of sins and guilt…we have to say that repentance is a great and important matter, a big program and a clear Divine fact.
Repentance does not take place when one just says with his tongue “astaghfirullah- I ask Allah to forgive me” with a little shyness inside him or he sheds some tears secretly or openly for there are many people who repent in this way but after a little time they return to commit the same sins and disobediences they have committed before.
Returning to commit sins is the clearest evidence showing that the true repentance has not been realized and that the light of the actual turning to Allah has not penetrated one’s soul. True repentance and actual turning to Allah are so important that a great part of the Qur’anic verses and holy traditions have talked about.
